I have a CAN BUS that is running at 125 KBPS. Also verified on an oscilloscope. I changed the bus speed setting on the Arduinos CAN BUS Shield sample code ( sample code from http://www.seeedstudio.com/wiki/CAN-BUS_Shield) purchased from (https://www.sparkfun.com/products/10039) but it does not stream anything on the serial terminal.

The code I tried is attached (its set at 500 kbps by default).

I am using a Microchip MCP2515DM-BM as the BUS I am trying to connect to. They have an application called MCP2515 Bus Monitor which displays interpreted BUS data along with the register settings. I'm guessing the Arduino Library needs to set the MCP2515 on the shield to listen mode.
